From what I understand, it really is just Lisp, not any language with multiple return values. The issue here is Lisp semantics for multiple return values being slightly cumbersome (but by no means difficult).


The discussion on github also mentions Lua (https://github.com/WebAssembly/spec/pull/215#issuecomment-17...), though it is true that this is coming from a Common Lisp developer.

From my point of view the feature is useful (efficient implementation without useless memory allocation) and the rebuttal looks slightly uninformed.

There are discussions about coroutines (https://github.com/WebAssembly/design/blob/master/FutureFeat...) and more generally about low-level capabilities (https://extensiblewebmanifesto.org/). Among those, we can see in the design document (https://github.com/WebAssembly/design/blob/4dec2849ad6d79fae...) a "Multiple Return Values" section with a "TODO" placeholder text: it seems that WebAssembly people want to implement MRV.


Go has multiple return values; could this also benefit go? I'd bet that that would garner more calls for MRV support in wasm if so.
